Valid for: 2018/19Decided by: PLED BI/RHDate of Decision: 2018-03-20

General Information

Compulsory for: BI2Language of instruction: The course will be given in Swedish

Aim

The objective of the course is to provide the students with
background knowledge about heat transport and combustion. The
course is also aimed at increasing the students'
engineering-related skills and their capabilities to construct and
analyse models.

Examination details

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)Assessment: The final grade is based on a written examination, home assignments (individual), computer laboratory (individual) and laboratory reports (work in group) as well as participation in obligatory seminars and laboratories

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.

PartsCode: 0116. Name: Fire Chemistry and Heat Transfer. Credits: 6,5. Grading scale: TH. Assessment: The examination process will be based on both an individual and a group-work basis. During the course, two sub-examinations will be given. During the course, the students will be responsible for three compulsory home assignments and one computer laboratory. Reporting of home assignments and computer laboratory will take place in seminars for which attendance is compulsory. At the end of the course there will be a written examination. Contents: Lectures and exercises treat fire risk for gaseous, liquid and solid fuels, fire development, smoke production, heat transfer and fire physics. Own problem solving work is therefore important for the course. Code: 0216. Name: Laboratory and Home Work. Credits: 6,5. Grading scale: UG. Assessment: The course is based, in part, on three laboratory sessions. Approved laboratory reports and attendance at all lab sessions are requirements for final certification. Contents: Contents of the laboratories: 1: Ignition; 2: Flammability limits; 3: Flame spread 4: Rate of heat release, smoke production from pool fires.

Course coordinator: Professor Patrick van Hees, Patrick.van_Hees@brand.lth.seFurther information: Group assignments require active participation. Each group member must individually be able to account for the content of the assignment. If a group member does not fulfill the demands of the group or ignores hers/his commitment, she/he can be reassigned to another group or get a fail result.
Some lectures may be given in English.
